Abstract: A system and method is provided that facilitates miter and notch identification for pattern sew line generation. A processor of the system may be configured to access a pattern data that defines a flat shape with cut lines corresponding to locations at which the shape is cut out of a material. Based on the pattern data, the processor may generate a computer-aided-design (CAD) model that includes a plurality of curves that define boundary edges of an object that corresponds to the shape defined by the pattern data. In addition, the processor may automatically identify portions of the boundary edges that correspond to alignment guides including at least one miter alignment guide, notch recess alignment guide, notch projection alignment guide, or combination thereof.
